Does he like me even a little?

I like this guy in my college. We have exchanged snapchat and Instagram and we often chat on snapchat. Last time one of his friend was teasing me because I was on his best friend list on Snapchat (so I am one of the person he talks to most) Also last time when I showed him a video, he leaned towards me to watch it. (Ok maybe because I was a little bit away from him) Also whenever someone is annoying me he looks at me first then he tries to make some noise to that person to show he/she should stop. I recently asked him who he liked and he replied with no one. I am so confused does he like me or not.
